I don't know the exact size of the rings/"oblongs" (Larry may be along & point out they're not true circles). on that target are but I'm guessing the group center is not much, if any, over an inch to the left & that's at 25 yards. What more could one ask for with fixed sights?
I would not want any Good Ol Boy From TN shot. Who knows, he may well have ancestors who rode alongside my Great Grandpa in the Confederate cavalry a'trying to Whup op on them Yankees.
I suppose everyone here is aware the NRA was founded by a couple of retired Union Generals licking their wounds because it had taken a better manned, better armed, better fed, better-equipped army four long bloody years to put down them Rebels, because they had been "Out Fought & Out Shot". This, of course, took place while Useless S Grant was the Prez.
